task_spec_short

task_spec_short is an agent for coding agents from ikonushok/agent-pack-designer. It costs 0 tokens per session (103 once invoked), scanned A, original, MIT.

A short written brief that defines the goal, boundaries, files, risks, validation method, and success criteria for a coding task. It also records what evidence was checked afterward.

In plain words
What is it for?
Use it before multi-file edits, validation claims, or release preparation to specify what may change, what must be tested, and what remains uncertain.
Why use it?
Non-trivial changes can expand in scope or be declared complete without enough proof. This brief makes the intended work and the required checks explicit.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

task_spec_short scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

task_spec_short is an agent published in the GitHub repository ikonushok/agent-pack-designer (10 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 103 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
